$5 DIY Gas Mask for Surviving Occupy Wall Street

As Lloyd Alter confirms, the Occupy movement is very much an environmental movement: off-the-grid camps are set up across the country, surprisingly with 21st-century tech. And since things have been known to get a little out of hand from time to time, this DIY gas mask by Gregg Horton is the perfect accessory for the revolution. It's cheap, easy and kinda cool.

Reduce, reuse and remember, the fifth of November!

Supplies

2 liter soda bottle

n95 rated face mask (Tear gas is a dust, not a gas so this will be perfect)

3. For this to work, you need to have a seal between your face and the bottle, and not the cute baby kind. Use duct tape to wrap the edges of the bottle adding extra layers as needed. You can check the seal by placing the mask against your face.
